Hang in...I'm acutally on the exact same search for my 97 SSEi. We are the exception to swapping out for a different sound. I like the quiet sleeper aspect.
Did a quick search and found Rockauto.com to be $137 shipped to my address in CT for the muffler and tail pipes for Vin 1...all should be the same for your car.
Muffler M2237 $81
Right tail M14727 $24
Left tail M14726 $24
Total $137 to my door.
Ooopsie. I just bought it.
Thanks for posting. I needed to get this done and have been poking along.
